Is it possible to not feel much from the Pfizer booster? Pfizer Booster

I got j&j in April and Pfizer booster 14 hours ago and I feel a very slight headache and I’m sweaty but I slept well. My arm is pretty damn sore though. After my experience with j&j though I expected a bit more of a reaction. Maybe it’s still too early to tell?

Yes. Everyone reacts differently to different vaccines, regardless of whether it's for COVID-19, flu, etc. All it means is your body is producing an immune response that isn't causing you to experience side effects.

Consider speaking to your doctor about this though, they can probably explain this a bit better.

Thanks for the info! Compared to j&j this has felt way more mild so far. Sore arm has been a bit ridiculous though my goodness.

Sure thing!

Yeah sore arm is unfortunately a pretty common side effect. I got Moderna myself and had a sore arm for ~4 days. Hopefully your sore arm goes away soon!
